Summoned as a Heroic Spirit in Anime World

He woke up with a boner. 

Yuki must have felt it too, because she rolled over and kissed him. 

Her kisses got more passionate as she rubbed her hand up and down his cock through his pants. 

Kaito lifted his hips a little to meet her touch. "Mmm," he moaned into her kisses.

She started to undo his pants and pushed them down, pulling his cock out to rub it with both hands. "Mm I love your cock, onii-chan," she said.

"I love yours too," he joked and she giggled and kissed him more. She stroked him for a while until he was hard, then she bent down and licked his cock. He gasped at her soft mouth on him. 

"Good girl," Kaito purred and pushed his hands into her soft hair. Yuki sucked him until she had taken as much of him in as she could, then she slowly pulled off and looked up at him with wide eyes. "Did I do a good job?" She asked.

"You did a great job," Kaito assured her.

"Yay!" She cheered and he laughed. "Can we keep going?"

"Of course we can," he replied. He sat up and pulled her into a kiss. "Are you ready to be fucked again?"

"Yes!" Yuki replied. She always answered so quickly when he asked her that.

Kaito kissed her more and started to undress her. 

She was already naked underneath, but she was still wearing her shirt and skirt. 

He pulled them off of her, enjoying how soft her skin felt under his hands. She sighed and arched into his touch.

"God you're hot," Kaito murmured and she blushed. He took her in his arms and pressed their bodies together, kissing her deeply as he pulled her under him.

Yuki's arms snaked around his back and she held him close to her. Kaito could feel her pussy against his cock and he pushed forward to get inside her. "Oh yes!" She cried out and Kaito moved his hips, pushing his cock deeper into her wet pussy.

"Fuck," he grunted into her neck. She felt so good. Her pussy was warm and tight around his dick.

"Oh god yes!" Yuki moaned. Her legs were around his hips and she lifted them higher up his back, holding him close and letting him fuck her more deeply.

Kaito rolled them over and sat up. She was straddling him again, her breasts bouncing up and down with every movement of her hips. "Mm your tits are so pretty," he said, looking down at her. "And your pussy feels amazing," he added and lifted his hips to thrust into her.

"I'm glad you think so," Yuki giggled. She bounced on his cock slowly and Kaito watched her as she did. He put one hand on her hip to help her, moving it up and down as she moved. "Oh god that's good," she moaned.

Kaito enjoyed the way she looked on top of him. Her hair was messy and her face was flushed with pleasure. 

He reached up and grabbed her breasts, squeezing them and pushing them together. 

"Mm," Yuki moaned and looked down at him, moving her hips faster.

He could tell that she wanted him to cum. She liked when he cummed inside her. Kaito got off the bed and helped her sit on the edge, putting his cock in and starting to thrust. 

"Oh yes!" Yuki cried. She held onto the edge of the bed and watched him as he moved inside her.

"You're so tight and hot," Kaito muttered. She was. She was fucking amazing.

"I love feeling your cock in me," Yuki said softly. Her cheeks were red and she was staring up at him with her big eyes.

"Oh my god yes," Kaito growled in response and fucked her harder. 

Yuki moved her hips to meet his thrusts, her moans getting louder.

Kaito grabbed her by the hips and fucked her faster, slamming his cock into her. 

Yuki cried out in pleasure and held onto him as much as she could. He leaned forward a little and licked her tits, sucking on her nipples.

"Oh yes! Oh my god, oh yes! Onii-chan! Onii-chan!" She screamed.

Kaito let go of one of her hips and reached up to cover her mouth with his hand, still holding her with one hand on her other hip. "Shh," he whispered. "Be quiet."

Yuki nodded and kept moving her hips, moaning and whimpering into his hand. Kaito fucked her until she started shaking around him, her pussy squeezing his cock tightly. "Oh my god! I'm gonna cum!" She cried and then came, shaking and moaning.

Kaito followed her, pulling out to cum all over her stomach. "Ah! Ah!" He grunted.

Yuki smiled up at him when he finished. "That was amazing," she said.

"It was," Kaito agreed.

"Can we fuck again?" She asked innocently and he laughed.

"I need to rest my cock a little first."

"Oh okay," she said with a pout. "I can lick your cock if you want. I'll help you get hard again." She got on her knees and started to lick his cock. Yuki was amazing at this. He didn't know why, but she had a great tongue. She licked all around his dick until he was fully hard again.

"Good job," he purred and pulled her onto his lap. They moved back onto the bed, with Kaito lying down and Yuki straddling him. She sat down onto his cock again and moved her hips.

He grabbed her tits and squeezed them, making her moan louder. "Oh yes, oh yes!" She gasped. He moved her up and down, slamming his cock into her.

She cried out again, moving her body faster. Kaito could tell she was close again. 

He moved faster, pumping his cock into her as deep as he could. 

"I'm gonna cum! I'm gonna cum again!" Yuki shrieked.

He moved faster again, slamming into her and she came around him, shaking and crying out. She collapsed onto his chest and Kaito held her there, still moving his hips. Yuki was still moaning softly.

"Are you sure you don't want to stop?" He asked her, running his hand up and down her back.

"No," she murmured. "I want to keep going." Her voice sounded tired, but Kaito knew she was okay.

"Okay," he said. "But we need to change positions." She nodded and got off of him. He sat up too and pulled her to straddle him again.

This time she turned around and he slipped into her from behind. She groaned and leaned back into him, resting her head on his chest. He wrapped his arms around her stomach and moved her, fucking her from behind.

"O-oh," Yuki moaned, looking up at him. She reached up behind her to run her fingers through his hair. "Oh god."

Kaito put his hands on her hips and moved them up and down, holding her in place. 

Yuki squeezed him with her pussy and gasped as he moved into her more deeply. He kissed her neck, licking and sucking as he did.

"You feel so good," he muttered into her skin.

"Thank you," she purred. She was moaning louder now, moving her hips as much as she could.

"You're gonna make me cum again," Kaito said.

"I'm gonna cum too," Yuki gasped.

"Oh god," Kaito grunted and moved faster. Yuki's moans got louder and her fingers tightened in his hair. "O-onii-chan!" She cried out as she came and he came with her, groaning into her neck.

They collapsed back onto the bed together and Kaito pulled her onto his chest again. They were both breathing heavily. 

"That was so fun," Yuki sighed happily.

"Are you going to ride me again?" He asked.

"Oh yes!" She answered and scooted to the edge of the bed. Kaito stood in front of her and she spread her legs. He stepped into her, letting his cock rub against her pussy. 

"Oh!" 

She gasped and rubbed herself against him.

"You want to sit on it again?" He asked teasingly.

"Please," she begged, blushing. He laughed and sat down in front of her. She straddled him again, sitting down onto his dick slowly. "Oh! Oh!" She moaned as he filled her up.

Kaito's eyes widened too. She was always so tight. He couldn't get over how good that felt. She started to move, bouncing up and down on his cock as she had before. "Mm yes," she sighed and closed her eyes. "That feels so good onii-chan."

"Mmm," he grunted, holding onto her hips and helping her up and down. He pushed his hands into her hair and pulled her head back to kiss her neck. "You're so pretty like this, Yuki."

"I love that," she purred and rubbed his face against her chest. He moved back down to kiss her tits. He loved kissing her tits.

"Oh! Oh my god!" She gasped in response to his mouth on her tits. "Don't forget about my pussy!" She laughed and he licked and sucked harder. "Oh god!"

Kaito looked at her. Her eyes were closed and she was moaning with every movement of their bodies. She was so beautiful. He had to cum again. "Oh god," he groaned. "Yuki, I'm gonna cum. You want me to cum in your mouth again?" He asked.

"Yes!" She replied. "Please onii-chan I want you to cum on my tits so I can lick it off." Kaito laughed and helped her up. They got off the bed, moving over to the mirror so they could both watch. She leaned down in front of him, looking over her shoulder at their reflection.

"Nice view," he murmured and she giggled in response, blushing.

He rubbed his cock against her pussy for a little bit, making sure she was wet and ready for him again. Then he pushed inside her, groaning at how warm and tight she was. She gasped and looked back at him.

"Mm, yes," he heard her moan as he moved in and out of her. He held her by the hips, fucking her hard and watching her in the mirror. She was bouncing and shaking in front of him.

"Ah! Oh god! Oh onii-chan!" She moaned, arching back against him.

He reached up around her to play with her tits as he fucked her. She moaned even louder as he pinched and squeezed them. "Mm, yes, yes," Yuki cried out.

Kaito reached down to play with her clit too, rubbing his finger in circles against it. She cried out louder, arching back into his touch. "I-I'm gonna cum!" Yuki screamed. "Oh oh oh! Ahahah!"

He didn't let her cum yet, he moved his finger away from her clit. "N-no!" She complained.

"I don't want you to cum yet," Kaito explained and she nodded.

He kept playing with her tits and thrusting into her, watching her as she got closer and closer. 

"Mm you're so pretty," he muttered. 

"So pretty with my cock in you." He was almost there, so he moved his fingers back to her clit, rubbing it again.

"Oh!" She moaned. "Thank you, onii-chan."

He moved his fingers in circles against her clit and she started to shake around him. "I'm cumming!" She cried out and he could feel her pussy tighten around him.

"Oh god!" He groaned in response. "I'm gonna too."

"Yes!" Yuki cheered. "Onii-chan, onii-chan! Cum with me, please!"

"I'm cumming," Kaito promised her and pulled out of her pussy. Yuki moved to kneel in front of him and he started stroking his dick until he came over her tits. She moaned happily as he covered her and then leaned forward to lick his cum off of her tits. Kaito groaned at her hot tongue on his cock.

"You're amazing," he told her.

"Thank you," Yuki replied, smiling up at him innocently. "I love doing this." She licked his cum off of herself, smiling when he groaned as she licked his cock too. "Do you want me to suck you again?" She asked and he nodded.

Yuki took him into her mouth and licked his shaft, running her tongue around the head of his dick. Kaito moaned softly. "Mmm, you're so good at this," he praised her.

She looked up at him as she sucked his cock, looking innocent. She made sure to lick all of his cock clean, even though he knew it wasn't clean yet since she still had cum on her tits.

He could feel himself getting hard again Yuki kept sucking him and then stopped to lick all up and down him again, rubbing her face against his cock.

"Oh god yes," he gasped. "You're too good at this."

Yuki giggled at him and kept sucking. Her mouth was so soft and warm, her tongue felt amazing. He ran his hands through her hair, enjoying the feeling of his fingers in her hair. "Mm so good," he sighed. "You're amazing."

She smiled up at him around his cock and then took him even further into her mouth, making sure to keep him wet with her spit. He could feel his balls getting tight.

"You're making me wanna cum," he warned her. Yuki looked up at him excitedly and nodded, taking him deeper into her mouth. She rubbed his balls with one hand and kept sucking on his cock.

"Oh fuck! Oh god!" He cried out. He was cumming again. She kept sucking, letting him shoot his load into her mouth.

When he finished, she pulled off of him and swallowed, smiling up at him proudly. "How was that?" She asked.

"It was amazing," he replied honestly. "You're always amazing." He reached down and pulled her up to sit on his lap. She blushed and looked away.

"You really like sucking my cock?" He asked curiously.

"I love it," she answered, looking up at him shyly.

"Good. I want you to keep doing that"

"I love sucking your cock," Yuki repeated, kissing him softly.

He laughed and hugged her back. "I really like it too."

She giggled happily and they went to take a shower together. After they washed off, Kaito wanted to fuck her again. So he laid her down on the bed and got between her legs, pushing into her slowly. "Mm!" Yuki moaned.

"I love your pussy," Kaito sighed. "It feels so good."

"I know," she replied. "I want you to fuck me." She wrapped her legs around his back again and held him close.

He pushed deeper into her, groaning. "I love this position too," he told her. "You're so hot like this." He kissed her more as he moved his hips. His cock slid easily in and out of her wet pussy, getting deeper and deeper with every thrust.

"Mmm," Yuki sighed. She squeezed her legs tighter around him and held onto him. "Oh, oh, oh, onii-chan," she muttered softly. Kaito kissed her again, enjoying the way their bodies fit together.

He fucked her slowly for a while, enjoying her warm pussy. Then he got onto his knees again, pulling her up to straddle him. "Oh yes," she gasped and he held her, moving her up and down on his dick.

Yuki moaned louder as they moved, holding onto his neck and kissing him back. "Oh! Oh god!" She cried out. "Yes, onii-chan!"

He kept moving her and she got louder again. "I-I-I'm gonna cum again," she cried out. "Cum with me! Please!" He nodded in response and started moving her faster.

"Oh oh oh!" She gasped with every movement of his hips. "O-onii-chan!"

He moved even faster, feeling her get closer and closer to cumming again. "I'm gonna," he grunted in response and pulled her down onto his cock.

She screamed as she came again, squeezing him with her pussy. Kaito cried out too, cumming again inside of her. He held onto her as they both came, kissing her to try and muffle their moans.

They collapsed onto the bed again, panting. "Fuck," Kaito panted. 

"You're fucking amazing."
